DRS means Dynamic Remote Scripted - a weird term, but it contains all of the essential components:
Games which are installed on the server only and dynamically transferred to the clients on demand. This allows players
to always have the latest versions (stable or unstable, on their command), while at the same time providing security
(all scripts are executed in a sand box) and efficiency (only the updated part are transferred, like with CVS).

the top-level directory. Each game consists of the DRS control file (like example.drs) and an optional description file (like example.dsc),
which is referred to as "control file" within the DRS control file. Let's show an example to make things clear:
